Title: Fail-safe type microwave compounding device
Inventor: OKUNO IZUMI
IPC: H04B1/04
Filed: 1978-12-13
Abstract: PURPOSE: To avoid the system breakdown even at the faulty time of the diode phase shifter by giving previously the fixed phase difference between the diode phase shifter and the semi-fixed phase shifter provided at the compounding circuit of the double signals.  
     CONSTITUTION: The output of hybrid 24 is supplied to semi-fixed phase shifter 7 and diode phase shifter 19. The phase difference of 40° is secured between the both phase shifters at the normal time. And the reduction of the output caused by the phase difference of 40° at the output compounding circuit is just 0.5dBm. And even in case the phase difference of 140° is caused at the compounding circuit owing to the fault of shifter 19, the output reduction is only 10dBm. Thus no system breakdown is caused. In order to secure the more perfect fail-safe system, logic board 11 is controlled to switch the circuit to the stand-by side in case the output reduction of more than 10dBm is detected through composite output detector 20.

Title: Printed interconnection board and manufacture thereof
Inventor: HIRABAYASHI TAKAYUKI
IPC: H05K3/24
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To provide a printed interconnection board and a method for manufacturing the same, in which semiconductor chips can be mounted in the manner of mounting flip chips with high reliability. SOLUTION: Cu electrodes 14 having superior conductivity are formed on an insulating substrate 12 of a printed interconnection board 10. Each of the Cu electrodes 14 is covered with an Ni layer 16, and the Ni layer 1 is further covered with an Au layer 18. Due to the covering of the Au layer 18, which is a non-oxidizing metallic layer, the Cu electrode 14 and the Ni layer 16 are prevented from being oxidized and covered with an insulating oxide film. In addition, due to the interposition of the Ni layer 16, which is a metallic layer of high hardness, when mounting semiconductor chips in a flip-chip-mounting manner, the individual projected electrodes of the semiconductor chips are not immersed in the individual Cu electrodes 14 which are, respectively covered with the Ni layers 16 on the printed interconnection board 10.  Consequently, each of the Cu electrodes 14, being covered with the Ni layer 16, is made adequately immersed in the insulating substrate 12.

Abstract: PURPOSE:To minimize drop-out of information to reproduce an optical disc well by detecting movement of the irradiated position of an irradiated light to return it to an original track position even if said irradiated position is moved because of a flaw or a pit forming defect on the optical disc. CONSTITUTION:If the irradiated light cannot be allowed to follow up the track on an optical disc M1 because of a flaw or a pit forming defect on the optical disc to move the irradiated position of the irradiated light to another track position, position information read by a position information reading means M4 and that estimated by a position information estimating means M5 do not coincide with each other, and this state is detected by an abnormality detecting means M6. Then, a control means M7 is operated to perform such control that position information read by the position information reading means M4 coincides wit that estimated by the position information estimating means M5, that is, the irradiated position of the irradiated light coincides with the original track position. Thus, information whose quantity corresponds to the extent of movement of the irradiated light is prevented from being dropped out to reproduce the optical disc well.

Abstract: PURPOSE:To attain talking without a sense of disorder by preventing background noise listened by a recipient from being unnecessarily increased. CONSTITUTION:A comparator 8 compares an output of an adder 3 with an output of a 2nd multiplier 9 and outputs an output of the adder 3 when an output of the adder 3 is smaller as an integration value and outputs an output of the 2nd multiplier 9 as an integration value when the output of the 2nd multiplier 9 is smaller.
